この考案は、例えばビニールハウスの被覆シートをシート巻軸に巻き込んで開 閉する被覆シート開閉装置のシート巻軸を回転駆動する手段として、あるいは前 記シート巻軸と同様に出力軸が負荷などによって正逆いずれの方向にも回転して は困るような用途に広く使用される、出力軸を入力軸によってのみ回転可能な回 転伝達装置に関する。 This invention is, for example, as a means for rotationally driving a sheet winding shaft of a covering sheet opening / closing device that winds a covering sheet of a vinyl house around the sheet winding shaft to open and close it, or like the above-described sheet winding shaft, when the output shaft is loaded by load or the like. The present invention relates to a rotation transmission device, which is widely used in applications where it is difficult to rotate in either forward or reverse directions, and whose output shaft can be rotated only by an input shaft.

従来、ビニールハウスのシート開閉装置などに使用される、出力軸を入力軸に よってのみ回転可能な回転伝達装置は、先の特開平１−２６６３５９号公報に記 載されて公知である。この回転伝達装置は、図３と図４に例示したように、出力 軸２と入力軸１は各々の中心線が一致する配置とされ、出力軸２の軸端部に被回 転体３を設けている。被回転体３の外周面部には、同被回転体３の半径線方向に ロック体押壁４ｂを形成し、接線方向に適度なくさび角度をもつロック体受底４ ａを形成したロック体受納部４が前後に隣接する２箇ずつの組合せで設けられて いる。そして、前後２個のロック体受底４ａを連続させるように後記の回転伝達 用凸部６を納める凸部受納部１０が円周方向に形成されている。前記ロック体受 納部４には、ロック体受底４ａの最深部と略同径のローラ５がロック体として設 置されている。一方、入力軸１の軸端部には回転ディスク９を設けている。この 回転ディスク９には、前記被回転体３の凸部受納部１０に位置する回転伝達用凸 部６が軸方向に突設され、これがロック体受納部４内に位置するローラ５と当接 する関係とされている。前記被回転体３と回転ディスク９は、被回転体３の外径 と略等しい内径の円筒形のケーシング８′内で突き合わされ、回転伝達用凸部６ を被回転体３の凸部受納部１０へ進入させた構成で組立てられている。前記ケー シング８′の回転は止められている。 Conventionally, a rotation transmission device which is used for a seat opening / closing device of a vinyl house and which can rotate an output shaft only by an input shaft is disclosed in the above-mentioned JP-A-1-266359. In this rotation transmission device, as illustrated in FIGS. 3 and 4, the output shaft 2 and the input shaft 1 are arranged so that their center lines coincide with each other, and the driven body 3 is provided at the shaft end portion of the output shaft 2. It is provided. On the outer peripheral surface of the rotated body 3, a lock body push wall 4b is formed in the radial direction of the rotated body 3, and a lock body receiving bottom 4a having a moderate wedge angle is formed in the tangential direction. The storage section 4 is provided in a combination of two adjoining front and rear. Further, a convex portion receiving portion 10 for accommodating a later-described rotation transmitting convex portion 6 is formed in the circumferential direction so that the front and rear two lock body receiving bottoms 4a are continuous. A roller 5 having a diameter substantially the same as the deepest part of the lock body receiving bottom 4a is installed in the lock body receiving portion 4 as a lock body. On the other hand, a rotary disk 9 is provided at the shaft end of the input shaft 1. On this rotating disk 9, a rotation transmitting convex portion 6 located in the convex portion receiving portion 10 of the rotated body 3 is axially projected, and this is provided with a roller 5 located in the lock body receiving portion 4. It is said that they are in contact with each other. The rotating body 3 and the rotating disk 9 are butted against each other in a cylindrical casing 8'having an inner diameter substantially equal to the outer diameter of the rotating body 3, and the rotation transmitting convex portion 6 is received in the convex portion of the rotating body 3. It is assembled in such a configuration that it has entered the portion 10. The rotation of the casing 8'is stopped.
【０００３】 この回転伝達装置は、出力軸２が正逆いずれかの方向に回転しようとすると、 接線方向にくさび角度をもつロック体受納部４のロック体受底４ａがロック体と してのローラ５を迫り上げて、ケーシング８′の内周面との間にくさびの如く食 い込ませてしまい、摩擦力で制止され回転不能となる。ところが、入力軸１が正 逆いずれかの方向に回転されると、入力軸１の回転伝達用凸部６が回転方向前側 のローラ５を後押しして同ローラ５をロック体受納部４内のゆるみ領域の中に位 置させると共に、更に前方のロック体押壁４ｂを押して被回転体３及び出力軸２ に回転を伝える。このとき回転伝達用凸部６よりも回転方向後側のローラ５は、 被回転体３のロック体押壁４ｂに後押しされて移動するが、ロック体受納部４内 のゆるみ領域の中に位置したままである。よって、入力軸１は出力軸２と１対１ の関係で正、逆いずれの方向にも自由に回転する。In this rotation transmission device, when the output shaft 2 tries to rotate in either forward or reverse direction, the lock body receiving bottom 4a of the lock body receiving portion 4 having a wedge angle in the tangential direction functions as a lock body. The roller 5 is pushed up and bites like a wedge between the roller 5 and the inner peripheral surface of the casing 8 ', and it is stopped by frictional force and cannot rotate. However, when the input shaft 1 is rotated in either the forward or reverse direction, the rotation transmitting convex portion 6 of the input shaft 1 pushes the roller 5 on the front side in the rotational direction to push the roller 5 in the lock body receiving portion 4. The lock body pushing wall 4b is pushed further forward and the rotation is transmitted to the rotated body 3 and the output shaft 2. At this time, the roller 5 on the rear side in the rotation direction with respect to the rotation transmitting convex portion 6 is moved by being pushed by the lock body push wall 4b of the rotated body 3, but within the loose area in the lock body receiving portion 4. It remains in place. Therefore, the input shaft 1 can freely rotate in either forward or reverse directions in a one-to-one relationship with the output shaft 2.
【０００４】[0004]
上記図３、図４に示した従来の回転伝達装置の場合は、ローラ５がロック体受 納部４のロック体受底４ａによる迫り上げによってケーシング８′の内周面との 間へくさびの如く食い込む動作で出力軸２の回転を阻止する構成であるため、動 作が複雑であり、長期間の繰り返し使用によってローラ５の内周面及びケーシン グ８′の内周面はガタガタに傷つき、円滑な動作を期待したがたい。また、この 回転伝達装置の生産性を上げ、かつ製作コストを下げる方策として出力軸２の被 回転体３及び入力軸１の回転ディスク９はアルミダイカスト品又は鍛造品として 成形するのが一般的であるが、そうすると必ず抜き勾配が発生し、それが軸方向 に長いため運動の不調を生じ易い。一方、ロック体としてのローラ５をはじめ、 出力軸２の被回転体３におけるロック体押壁４ｂ，ロック体受底４ａや入力軸の 回転伝達用凸部６並びにケーシング８′など、部品点数が多いので組立ても容易 でない。 In the case of the conventional rotation transmission device shown in FIGS. 3 and 4, the roller 5 is pushed up by the lock body receiving bottom 4a of the lock body receiving portion 4 so as to form a wedge between the roller 5 and the inner peripheral surface of the casing 8 '. Since the rotation of the output shaft 2 is prevented by the biting operation as described above, the operation is complicated and the inner peripheral surface of the roller 5 and the inner peripheral surface of the casing 8'are rattlingly scratched by repeated use for a long time. It is difficult to expect smooth operation. In addition, as a measure to increase the productivity of this rotation transmission device and to reduce the manufacturing cost, it is common to mold the rotating body 3 of the output shaft 2 and the rotating disk 9 of the input shaft 1 as an aluminum die cast product or a forged product. However, if this happens, a draft will always occur, and since it is long in the axial direction, it is likely to cause a movement disorder. On the other hand, the number of parts such as the roller 5 as a lock body, the lock body push wall 4b in the rotated body 3 of the output shaft 2, the lock body receiving bottom 4a, the rotation transmitting convex portion 6 of the input shaft, and the casing 8'is small. There are many, so it is not easy to assemble.
【０００５】 従って、本考案の目的は、加工が容易な部品で構成され、部品点数も少なく、 組立てが容易で、回転の動作が比較的に単純で、長期間使用しても円滑な回転運 動及び性能上の信頼性を保持できる構成に改良した回転伝達装置を提供すること である。Therefore, an object of the present invention is to be composed of parts that can be easily processed, have a small number of parts, be easy to assemble, have a relatively simple rotation operation, and have a smooth rotary operation even after long-term use. It is an object of the present invention to provide an improved rotation transmission device having a configuration capable of maintaining dynamic and performance reliability.

上記従来技術の課題を解決するための手段として、本考案に係る出力軸を入力 軸によって回転可能な回転伝達装置は、 出力軸２２と入力軸２１は各々の中心線が一致する一連的な配置とされ、出力 軸２２の内端部に被回転体２３が設けられていること、 前記被回転体２３の端面の円周の約１／２部分に一端を被回転体中に埋込み固 定され他端を軸方向に突出された少なくとも２本の伝達ピン２４が設けられ、前 記被回転体２３の端面の円周の残る約１／２部分に一端を被回転体中に埋込み固 定され他端を軸方向に突出された少なくとも２本のロックピン２５が設けられて いること、 内周面の対称位置に２つの凹部２７、及び前記ロックピン２５と当接され半径 方向外向きに拡径させる２つのロックカム面２８を備え、半径方向内向きへの復 元力を有するスナップリング形状の摩擦板２６が少なくとも１枚、その外周面が ケーシング２９の内周面２９ａに対して若干ルーズな状態で設置され軸方向に突 出された前記伝達ピン２４及びロックピン２５が内周側を貫通されていること、 前記入力軸２１の内端部の端面から軸方向に突き出る駆動板３０が設けられ、 この駆動板３０は前記伝達ピン２４と前記ロックピン２５との中間に位置され、 該駆動板３０の半径方向の両端が前記摩擦板２６の凹部２７内に位置されている こと、 前記被回転体２３と摩擦板２６及び駆動板３０は円筒形のケーシング２９内で 組立てられ、前記ケーシング２９の回転は止められていること、 をそれぞれ特徴とする。 As a means for solving the above-mentioned problems of the prior art, in a rotation transmission device capable of rotating an output shaft according to the present invention by an input shaft, an output shaft 22 and an input shaft 21 are arranged in a series so that their center lines coincide with each other. The rotating body 23 is provided on the inner end of the output shaft 22, and one end is embedded and fixed in the rotating body at about half the circumference of the end face of the rotating body 23. At least two transmission pins 24 are provided, the other end of which is projected in the axial direction, and one end is embedded and fixed in the rotated body at the remaining half of the circumference of the end surface of the rotated body 23. At least two lock pins 25 projecting in the axial direction at the other end are provided, and two recesses 27 are provided at symmetrical positions on the inner peripheral surface, and the lock pins 25 are in contact with the lock pins 25 and expand outward in the radial direction. Provided with two lock cam surfaces 28 for making the diameter inward in the radial direction Of at least one snap ring-shaped friction plate 26 having a restoring force, the outer peripheral surface of which is slightly loosened with respect to the inner peripheral surface 29a of the casing 29, and the transmission pin 24 protruding in the axial direction. And the lock pin 25 is pierced on the inner peripheral side, and a drive plate 30 is provided that projects in the axial direction from the end surface of the inner end portion of the input shaft 21. The drive plate 30 includes the transmission pin 24 and the lock pin. 25, and both ends of the drive plate 30 in the radial direction are located in the recesses 27 of the friction plate 26. The rotated body 23, the friction plate 26, and the drive plate 30 have a cylindrical shape. It is assembled in the casing 29, and the rotation of the casing 29 is stopped.
【０００７】[0007]
入力軸２１を回転させると、駆動板３０がまず摩擦板２６の凹部２７の端に当 接して回転する。これと前後して駆動板３０は伝達ピン２４に当接し、該伝達ピ ン２４を介して被回転体２３に回転を伝達する。その間、ロックピン２５がロッ クカム面２８と当接するまでに至らない。従って、入力軸２１の回転は駆動板３ ０から伝達ピン２４及び被回転体２３を経て出力軸２２に伝達され、出力軸２２ は同一方向に同一速度で回転される。一つの駆動板３０につき２本の伝達ピン２ ４を設けているので、出力軸２２は入力軸２１によって、正、逆双方向に自在に 回転される。 When the input shaft 21 is rotated, the drive plate 30 first contacts the end of the recess 27 of the friction plate 26 and rotates. Around this time, the drive plate 30 contacts the transmission pin 24 and transmits the rotation to the rotated body 23 via the transmission pin 24. Meanwhile, the lock pin 25 does not come into contact with the lock cam surface 28. Therefore, the rotation of the input shaft 21 is transmitted from the drive plate 30 to the output shaft 22 via the transmission pin 24 and the rotated body 23, and the output shaft 22 is rotated in the same direction at the same speed. Since two transmission pins 24 are provided for one drive plate 30, the output shaft 22 is freely rotated by the input shaft 21 in both forward and reverse directions.
【０００８】 逆に、出力軸２２を回転させると、直ちにロックピン２５が摩擦板２６のロッ クカム面２８に当接し、摩擦板２６を半径方向外向きに拡開させて摩擦板２６の 外周面２６ｂがケーシング２９の内周面２９ａに圧接され、その摩擦力で被回転 体２３の回転は不能となり、結局、出力軸２２は回転不可能である。この場合も 、２本のロックピン２５が各々対をなす２つのロックカム面２８と当接する構成 なので、出力軸２２は正、逆双方向に回転不能である。On the contrary, when the output shaft 22 is rotated, the lock pin 25 immediately comes into contact with the lock cam surface 28 of the friction plate 26, and the friction plate 26 is expanded radially outward so that the outer peripheral surface of the friction plate 26 is expanded. 26b is pressed against the inner peripheral surface 29a of the casing 29, and the frictional force disables rotation of the rotated body 23, and eventually the output shaft 22 cannot rotate. Also in this case, since the two lock pins 25 are in contact with the pair of lock cam surfaces 28, respectively, the output shaft 22 cannot rotate in both forward and reverse directions.
【０００９】[0009]
以下に、図示した本考案の実施例を説明する。 図１と図２に示した回転伝達装置において、符号図中２１が入力軸で、２２は 出力軸である。入力軸２１と出力軸２２は各々の中心線が一致するように一連に 対向配置されている。 Hereinafter, the illustrated embodiment of the present invention will be described. In the rotation transmitting device shown in FIG. 1 and FIG. 2, reference numeral 21 in the drawings is an input shaft and 22 is an output shaft. The input shaft 21 and the output shaft 22 are arranged in series so as to face each other so that their center lines coincide with each other.
【００１０】 出力軸２２の軸端部に被回転体２３が一体的に設けられ、該被回転体２３に一 端を埋込み固定され他端を軸方向に突き出された伝達ピン２４およびロックピン ２５が設置されている。伝達ピン２４は、図２に示したように、被回転体２３の 端面の円周の約１／２部分に説明の便宜上表示した横中心線Ｂ−Ｂに対して角度 αをなす左右対称な位置に２本埋込まれている。該伝達ピン２４は図２の中立状 態において後述する駆動板に近接する位置に設けられている。他方のロックピン ２５は、図２に示したように、被回転体２３の端面の円周の残る約１／２部分で あって前記の横中心線Ｂ−Ｂに対して角度βをなす左右対称な位置に２本埋込ま れている。該ロックピン２５は、後述するロックカム面に近接する位置に設けら れている。上記の角度αは角度βに比べて小さく設定され、本装置の円滑な動作 を可能にしている。A rotating body 23 is integrally provided at the shaft end portion of the output shaft 22, and one end is embedded and fixed in the rotating body 23 and the other end is projected in the axial direction, and a lock pin 25. Is installed. As shown in FIG. 2, the transmission pin 24 is bilaterally symmetric with respect to the horizontal center line B-B shown on the half of the circumference of the end face of the rotated body 23 for convenience of description. Two are buried in the position. The transmission pin 24 is provided at a position close to a drive plate which will be described later in the neutral state of FIG. The other lock pin 25 is, as shown in FIG. 2, a left and right half of the circumference of the end face of the rotated body 23 and forms an angle β with respect to the horizontal center line BB. Two are embedded in symmetrical positions. The lock pin 25 is provided at a position close to a lock cam surface described later. The angle α is set to be smaller than the angle β, which enables smooth operation of the device.
【００１１】 前記の如く軸方向に突出された伝達ピン２４及びロックピン２５は、図２に示 した摩擦板２６の内周側を貫通されている。摩擦板２６は、ばね鋼板を打ち抜き プレス加工等によって略スナップリング形状に製作されたもので、その内周面２ ６ａには前記の横中心線Ｂ−Ｂ上の左右対称な位置に凹部２７が設けられ、該凹 部２７に近接する左右対称な位置にロックカム面２８を設けた構成とされている 。この摩擦板２６の外周面２６ｂは、円筒形のケーシング２９の内周面２９ａに 対して回転自在な程度に若干ルーズな直径差で設置されている。前記摩擦板２６ は略スナップリング形状に形成されているため、拡開可能であるが、半径方向内 向きへの復元力を発生する。内周面２６ａの前記ロックカム面２８は、内向きに 半径が変化する内カムの一種で、その変化する手前の近傍位置に前記ロックピン ２５が配置されている。The transmission pin 24 and the lock pin 25 which are projected in the axial direction as described above penetrate the inner peripheral side of the friction plate 26 shown in FIG. The friction plate 26 is manufactured by punching a spring steel plate into a substantially snap ring shape, and the inner peripheral surface 26a of the friction plate 26 is provided with recesses 27 at symmetrical positions on the horizontal center line BB. The lock cam surface 28 is provided at a symmetrical position close to the concave portion 27. The outer peripheral surface 26b of the friction plate 26 is installed with a slightly loose diameter difference so as to be rotatable with respect to the inner peripheral surface 29a of the cylindrical casing 29. Since the friction plate 26 is formed in a substantially snap ring shape, it can be expanded, but a restoring force inward in the radial direction is generated. The lock cam surface 28 of the inner peripheral surface 26a is a kind of inner cam whose radius changes inwardly, and the lock pin 25 is arranged in the vicinity of the front side where the radius changes.
【００１２】 従って、図２の中立状態から出力軸２２の被回転体２３が回転すると、直ちに ロックピン２５が回転方向前方のロックカム面２８に当接し、前記ロックカム面 ２８のリフトに従がって摩擦板２６を半径方向外向きへ拡開させる。その結果、 摩擦板２６の外周面２６ｂがケーシング２９の内周面に圧接され、強力な摩擦力 を発生して回転不能となる。２本のロックピン２５及びこれに対応する２個のロ ックカム面２８の構成により、出力軸２２は、正、逆双方向に回転不能である。 摩擦板２６は本実施例では一枚使用しているが、複数枚重ね合わせて使用してよ り強力で確実な動作を確保することもできる。Therefore, when the rotated body 23 of the output shaft 22 rotates from the neutral state of FIG. 2, the lock pin 25 immediately contacts the lock cam surface 28 on the front side in the rotation direction, and follows the lift of the lock cam surface 28. The friction plate 26 is expanded radially outward. As a result, the outer peripheral surface 26b of the friction plate 26 is brought into pressure contact with the inner peripheral surface of the casing 29, and a strong frictional force is generated to make the rotation impossible. Due to the configuration of the two lock pins 25 and the two lock cam surfaces 28 corresponding thereto, the output shaft 22 cannot rotate in both the forward and reverse directions. Although one friction plate 26 is used in this embodiment, it is also possible to secure a stronger and more reliable operation by using a plurality of friction plates 26 stacked on top of each other.
【００１３】 一方、入力軸２１の内端部の端面からは、軸方向に突出する駆動板３０が設け られている。前記駆動板３０は、図２に示したように、前記伝達ピン２４とロッ クピン２５の中間の横中心線Ｂ−Ｂの位置に平板状に設置され、この駆動板３０ の半径方向の両端は前記摩擦板２６の凹部２７内に位置して凹部２７の端に当接 する構成とされている。On the other hand, a drive plate 30 projecting in the axial direction is provided from the end surface of the inner end portion of the input shaft 21. As shown in FIG. 2, the drive plate 30 is installed in a flat plate shape at a position of a horizontal center line BB between the transmission pin 24 and the lock pin 25. The friction plate 26 is located in the recess 27 and is in contact with the end of the recess 27.
【００１４】 したがって、入力軸２１に正逆いずれかの回転を与えると、駆動板３０が回転 して先ず摩擦板２６の凹部２７の端に当接し、摩擦板２６を回転させる。その直 後に駆動板３０は伝達ピン２４に当接する。この時点でもまだロックピン２５と ロックカム面２８とは当接するに至らないため、駆動板３０は伝達ピン２４を通 じて被回転体２３及び出力軸２２に回転を伝達する。即ち、摩擦板２６の外周面 ２６ｂとケーシング２９の内周面２９ａとはルーズな関係を保って自由に回転す る。かくして入力軸２１の回転は正逆いずれの方向にも自由に行われ、その回転 は駆動板２６から伝達ピン２４、被回転体２３を経て出力軸２２へ伝達され、出 力軸２２は同一方向に同一速度で回転される。Therefore, when the input shaft 21 is rotated either forward or backward, the drive plate 30 rotates and first comes into contact with the end of the concave portion 27 of the friction plate 26 to rotate the friction plate 26. Immediately thereafter, the drive plate 30 contacts the transmission pin 24. At this point in time, the lock pin 25 and the lock cam surface 28 still do not come into contact with each other, so that the drive plate 30 transmits the rotation to the rotated body 23 and the output shaft 22 through the transmission pin 24. That is, the outer peripheral surface 26b of the friction plate 26 and the inner peripheral surface 29a of the casing 29 freely rotate while maintaining a loose relationship. Thus, the rotation of the input shaft 21 is freely performed in either forward or reverse directions, and the rotation is transmitted from the drive plate 26 to the output shaft 22 via the transmission pin 24 and the rotated body 23, and the output shaft 22 is in the same direction. Are rotated at the same speed.
【００１５】 尚、入力軸２１と駆動板３０の中間部に公知の減速機構、例えば遊星歯車式減 速機構を組入れ、入力軸２１の回転負荷を数分の一に減らす構成で実施すること も行なわれる。 ケーシング２９の端面はサイドカバー３１で密閉されている。前記サイドカバ ー３１のボス部に入力軸２１及び出力軸２２の軸受３１ａが設けられている。ケ ーシング２９は、特に図示することは省略した固定手段により回転しないように 止められている。本実施例の場合、前記伝達ピン２４，ロックピン２５，凹部２ ７及びロックカム面２８は、一つの駆動板３０に対して左右対称な一対として設 けられているが、駆動板３０を直角４方向に設けると、前記の各要素は２対ずつ 設けられることになる。A known reduction mechanism such as a planetary gear type deceleration mechanism may be incorporated in the intermediate portion between the input shaft 21 and the drive plate 30 to reduce the rotational load of the input shaft 21 to a fraction. Done. The end surface of the casing 29 is sealed by a side cover 31. Bearings 31 a for the input shaft 21 and the output shaft 22 are provided on the boss portion of the side cover 31. The casing 29 is fixed so as not to rotate by a fixing means (not shown). In the case of the present embodiment, the transmission pin 24, the lock pin 25, the concave portion 27 and the lock cam surface 28 are provided as a pair of left and right symmetrical with respect to one drive plate 30, but the drive plate 30 is formed at a right angle 4. When provided in the direction, two pairs of each of the above elements will be provided.
【００１６】 以上要するに、出力軸２２は外力や負荷等によって回転することは正、逆双方 向に絶対的に不可能であり、この出力軸２２は入力軸２１によってのみ正、逆双 方向に自由に回転させることができる。従って、この回転伝達装置は、出力軸２ ２が負荷等によって勝手に又は不用意に回転しては困るような用途、又は出力軸 ２２の回転位置の確実な位置決めが必要な用途に好適に使用できる。In summary, it is absolutely impossible for the output shaft 22 to rotate in both forward and reverse directions due to external force, load, etc., and the output shaft 22 is free to rotate in both forward and reverse directions only by the input shaft 21. Can be rotated. Therefore, this rotation transmission device is suitably used for applications in which the output shaft 22 does not rotate freely or carelessly due to a load or the like, or applications in which the rotational position of the output shaft 22 must be reliably positioned. it can.
